DBjAFT-RIGGING FOR ROLLING-STOCK.

oiasss.

To all whom it may concern:

Be it known that I, HAmiAr-I- ISTRAUB, a.

citizen of the United States, residing at Ensley, county of Jefferson, State of Alabama, have invented certain new and useful Improvements in Draft-Rigging for Rolling-Stock; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to improvements in draft gear for rolling stock.

In freight and other cars, whether the frame is wooden or steel, there is a great the exact details illustrated and described,

still for the purpose of disclosure, reference is had to the accompanying drawings, forming a part of this application, in which drawings like characters designate the same parts in the several views and in which:

Figure 1 is a plan view of a car frame equipped with my invention; Fig. 2 isan inverted plan view of a portion of a car frame with my invention applied and the parts locked in their assembled position; Fig. 3 is a similar view to Fig. 2 with one portion of the draw bar casing removed and with the draw bar retaining plate removed and. showing the rear yoke of the draw bar with its follower plates and springs; Fig. 4

is a central longitudinal section on the line.

' Application' 'filed November 23, 1910. Serial No. 593,910.

In carrying out my invention, I provide the outside faces of the center sills with a short track 6, near each end of the car frame and associated with a detachably mounted support for the rear endof each of the draw bars, which detachably mounted supports are hereinafter referred to as the draw bar casings. Each draw bar casing may consist of a two part casting as shown, the parts being of the same construction and on their inner lower face being recessed as at 7, the recess terminating in a slot 8 extending transversely of the casing. The upper edge of these castings are also recessed forming.

flat shoulders or hearing faces 9 adapted to '1 seat on the underneath faces of thecenter sills and also providing upwardly disposed projections 10, having bearing faces adapted to rest against the side walls of said center sills; The bearing faces of the projections 10 are provided with opposed grooves 11, adapted to receive the track members 6, this arrangement preventing the vertical dis placement of the casing.

11 designates the draw bar supported at its forward end by the retaining plate 12 (Fig. 2) spaced from the end sill by the spacing blocks 13, the spacing blocks and retaming plate being secured' to the end sill by bolts l t. The inner end of the draw bar I is provided with a yoke 15, adapted toproect through one of the slots-8 formed in the draw bar casing and lie within the pocket formed by the recesses, 7. Within the yoke 15 are a pair of follower plates 16, and these follower plates are normally held against the end of the draw bar and the end of the yoke by coiled or spacing springs .1? interposed between said follower plates. It will be observed that the follower plates 16 are of a dimension to fit within the pocket formed by the recesses or chambers .7, with. sutficient clearance to allow slight play and the projecting endsof the forward follower block will restagainst the forward wall of the recess 7, while the projecting ends of the rear follower block will rest against the rear walls of the recess 7 formed in the rear casting, when the two parts thereof are secured face to face together. By this construction, it will be seen that the draw bar is securely coupled within the draw bar casing but free toswing laterally a limited distance and also free to move longitudinally against the action of said springs, the arrangement compensating for pulling and compression strams or stresses. When in their assembled position, these castings are held together by the tie rods 18, extending substantially the length of the car and connecting the castings at the forward'and rear ends of the car frame. The castings are also secured to the. forward and rear end sills of the frame by'tie bolts 19. I also provide an abutment member for holdingthe cast-' ings squarely in position when resisting compression. stresses" due to impact of car bumping and also to hold the, castings squarely in position when resisting .pulling stresses; This abutment member-consists of a head block 20, having its upper face 21 flush with the upper-face of the center sills,

- mit' the head block to be moved longitudibeing disposed therebetween at the rear of theidraw-"barcastings. The side faces of the head blockare recessed as .at 22 to pernally between the sills, the recesses 22 allowing the heads of the bolts 23 to ride therethrough. The bolts 23 secure the track 6 25 in position' From the headblock 29 there depends an integral portion 24 which is of a width suffi'cient to straddle the center sills and form-' ing with the head block shoulders 25 adapted to rest underneath the center sills.

vide a clearance space for the back wall of i the yoke 15 when the coupler is forced backbe obvious that the connection between the wardly against the compression of the springs. The head block ,of the abutment membenisalso provided with an aperture 27 through which is passed a tie bolt 27 c'onnectingthe abutment member with the end sill. I c

From the foregoing, the operation of the invention will be readily seen and it will draw head and its casting compensates for pulling and compression strains while allow-' ing the draw head to swing freely for turning curves and it will be observed that the tylng of the two draw bar casingstogether provides a construction insuring rigidity,

' the whole saving the frame work of the car from the reat strainsthat they are ordi- 'narilysub ected to. It will further beobserved that by the construction illustrated and described, the castings to which the draw bar is connected, are not bolted or otherwise directly secured to the center sills,

- as in other. forms of devices where the-draft rigging is bolted to the'center sills by vertically disposed bolts causing the center sills to split, a disadvantageous feature entirely eliminated by my construction and which differentiates same from any. prior construction that I am aware of.

Having thus described a practical. and preferred embodiment'of the invention, the particular features of novelty will now be This depending portion is recessed as at 26 to propointed-out more succinctly in the following claims.

1. The combination of a car frame, a

draw bar at each end of said car frame, a detachably mounted support for the rear end of eachv of said draw bars,'connections between the rear end of'each of said draw bars and its dc'tachably mounted support; ,tie bolts connecting said detachably mount ed supports with their adjacent end sills of.

the car frame, and tie rods connecting said detachably mounted supports together, sub stantially as described.

2. The combination of a car frame, a draw bar at each end thereof, a detachably mount ed support for each of said-draw bars, connections between the rear end ofeach of I said drawbars and its adjacent detachably mounted support, including as an element cushioning means, an abutment for each of said detachably mounted supports, slidably mounted on" the center sills of said frame, intermediate 'of' said detachably mounted supports and adapted to engage theinside faces thereof, tie bolts forcing said abutments in engagement with said detachably mounted supports, and tie rods connecting said detachably-mounted supports together; for holding same snugly against said abutments, substantially as described.

3. The combination of a car frame, :1. cas

gmitting said draw'bar to swing laterally and to reciprocate longitudinally under limited restraint, tie bolts connecting the inner castings of said casings with their adjacent end sills of-the car frame, and tie rods connecting the outer castings of said.
